United States Patent 3,087,763 LABORATORY TABLE FOR RESEARCH WORK INHOSPITALS AND THE LIKE Ake Lars Fredrik J acobsson, 1A ViktorRydbergsgatan, Gothenburg, Sweden Filed Nov. 9, 1961, Ser. No. 151,316 1Claim. (Cl. 108-13) The present invention relates to wall tables forlaboratories in hospitals and similar institutions. There is a need forsuch tables in certain instances because of the expanding research atthe present time, where change of locales and lines of research veryoften lead to costly rearrangements in the locales as well as newinstallations in old and new laboratory rooms.

It is an object of this invention to provide a lengthy table havingmeans to be secured in position along the wall of a room, and capable ofbeing changed and adjusted to suit the development of work in alaboratory room.

It is a further object of this invention to provide a lengthy tablehaving means to be secured in position along a room wall, and which willraise no difficulties on moving to new locales and no damage to the oldlocales, so that both locales will be promptly ready for their intendednew use.

It is another object of this invention to provide a lengthy table havingmeans to be secured in position along a room wall, and which has adesign which will essentially facilitate a change of the breadth of thetable in the cross direction of the wall.

A further object of this invention is to provide a lengthy table havingmeans to be secured in position along a room wall, and in which a levelof a portion of the table is capable of being changed with respect toanother portion thereof.

With these and other objects in view the invention essentially consistsin that the table, being a combination of at least two lengthy tablespositioned side by side in front of each other along a room wall, hastwo table plates, preferably of different breadth, each carried at thenecessary supporting places by a cross directed bracket, these bracketsbeing separate brackets extending substantially along the whole breadthof its corresponding table plate, the inner bracket adjacent to the wallbeing arranged to be connected at its inner end to a wall connection andat its outer end to an outer freestanding pillar, the outer bracketbeing connected solely to said pillar, the connection consisting ofcoupling parts so designed that the coupling part of the outer bracketis similar to at least the inner end coupling part of the inner bracket,so that the preferably broader outer table plate will be able to replacefrom its normal outer position both of the two normally assembled tableplates by coupling the outer bracket directly to the Wall connection, orallow the inner, preferably narrower, table plate to remain as a soleplate for the table, the two coupling parts of the coupling having acontinuous adjustment relative to each other in the vertical directionpermitting the table plates to obtain arbitrary level positions.

In the drawing:

FIGURE 1 is a side elevational view of the table,

FIGURE 2 a plan view thereof, and

FIGURE 3 is a side view of the table on a smaller scale.

The laboratory table consists in the embodiment shown of two lengthytable plates A and B, preferably of different breadth, lying with theirlong edges side by side in front of each other and of the wall 3. Eachtable plate is supported by brackets 1 and 2 at places where thesupporting is deemed necessary, the brackets being in line ice with eachother and cross-directed against the length direction of the table andof the wall. These brackets are detachably coupled to each other,preferably by means of a between part, and the inner bracket 2 next tothe Wall is detachably coupled to a wall connection which has the shapeof a coupling part 4. The between part between the brackets and theouter bracket has its common coupling in the form of the couplingbetween the wall and the inner end of the inner bracket, permitting theouter bracket with its preferably broader table plate to be directlyconnected with the wall coupling part, when the inner bracket isremoved.

The brackets as shown are made of iron or other metal sheets bent in aU-shape with the long U-opening turned upwards. The breadth of thebrackets in the vertical direction preferably increases towards theircoupling end or ends.

The inner bracket 2 is carried at one end by the wall coupling part 4and at the other end by a pillar 5 serving as a between part between thetwo brackets. The wall coupling part consists of a vertical bar with aC-prof1le in cross section, said bar, fastened on the floor, beingattached to the wall in a suitable detachable way. The outer pillar 5for the inner bracket 2 consists of two vertical C-profiled bar-s 5a, 5bsimilar to the vertical wall bar and welded together with their backsagainst each other, said pillar being adjustable in the verticaldirection by means of a foot screw 6. The C-bar 4 of the wallconstitutes the one coupling part for the connection of the innerbracket 2, and the outer C-bar 5a of the pillar constitutes the onecoupling part for the connection of the outer bracket 1. The opposingend of each bracket has a T-head 7a as a corresponding coupling partsuited to grip into the C-bar, said T-head being provided with a leg 7bwelded within the U-bracket between its two side walls along the upperlengthy opening 8 between them. The leg in side view has the shape of alengthy lying Z causing the T-head to have a lowered position beneaththe upper edge of the bracket, as shown in FIG- URE l. A locking bolt 9in the oblique direction is screwed through the T-head from below andextends out through the bottom of the bracket with a bolt head 9aserving as a grip for the turning of the locking bolt. This bolt ispositioned in such a way that the end of the same, screwed through thehead, will abut against the inner surface of the back of the C-bar andforce the T-head strongly against the inner surtace of the forward wallof the C-bar.

The brackets have a larger breadth in vertical direction near theirsupported ends. This end of each bracket has an upper portion cut away,as shown in the drawing, giving the lower portion the shape of aprotruding nose 1a, 2a, 2a which enters through the vertical lengthyopening of the corresponding G-bar to bear against the inner backsurface of the C-bar. The inner bracket 2 may, if desired, have anarbitrary connection with the pillar, but in the preferred embodimentthe connection also consists of a coupling similar to the one on thewall. This has a certain advantage not only in the manufacturing butalso in that it will be convenient to have between-lying brackets withlike ends which will facilitate the mounting as well as a building up ofmore than two table plates side by side to increase the total breadth ofthe table if desired.

By the locking bolt the bracket is steadily maintained at its C-barindependent of its mounted position above the floor. Said position maybe arbitrarily chosen along the C-bar. The load on the bracket will helpto maintain the bracket in position as the load pressure causes apressing of the bracket nose against the inner surface of the back ofthe C-bar and increases the pressure of wardly between the walls of thebracket.

the T-head against the opposing surface of the *C-bar.

As will be apparent, the device will permit three difierent tablebreadths to be used, viz a table plate on the inner bracket alone, atable plate with the outer bracket alone replacing the inner bracketwith its table plate, as well as the two brackets with their tableplates in assembled use, as shown in the drawing.

The table plates are de'tachably connected to the brackets, for instanceby screws 10 pressing against flat iron tongues 11 from the table platesdirected down- As the coupling design permits the brackets to bepositioned on different heights the inner table plate may, for instance,be positioned higher than the outer table plate, with a -vertical wallstrip between them as a holder for electric bulbs, gas taps and thelike. slidable in the other.

The'inner vertical C-bar 4 and the outer pillar 5 may be free standingon the floor or detachably secured to the same.

What I claim is:

A laboratory table for research work in hospitals and the likeconsisting of an assembling of at least two lengthy table platespreferably of different breadth to be disposed side by side in front ofeach other along the wall of the laboratory room, the table plates beingat each necessary support place supported by a cross-directed bracketfor each of them, the two brackets being executed as separate bracketscarried by supports and stretching themselves in line with each otheressentially along the whole breadth of the corresponding table plate,the inner bracket next to the wall being coupled with The one couplingpart is its one end to a wall connection and With its other outer end toa pillar or the like standing on the floor, the outer bracket beingcoupled solely to said pillar, the coupling part of the outer bracketbeing alike the coupling part at the inner end of the inner bracket,permitting the outer bracket to be directly coupled to the wallconnection when the inner bracket is removed, enabling the use of alaboratory table of three difierent breadths, viz the two table platesassembled, the inner table plate alone, and the outer table plate alonereplacing the inner table plate, the couplings being built up bycoupling parts having a continuous adjustment path relatively each otherin the vertical direction permitting thetable plates to obtain arbitrarylevel positions, the one coupling part for each bracket consisting of aseparate vertical C-profiled bar, and the other coupling part of aT-member protruding from the bracket end, the T-head thereof positionedwithin the T-bar and the leg thereof extending out through the lengthyopening of the C-bar, a locking screw belonging to the T-member being ininclined position screwed through the T-head to abut against the innersurface of the back wall of the C-bar causing the T-head to be clampedagainst the inner surface of the forward wall of the C-bar.
